Details?
The ones you sent were 32bit issues (with 1024 bytes frame-size-warning):
fs/select.c:991:1: warning: the frame size of 1032 bytes is larger than 1024 bytes [-Wframe-larger-than=]
arch/parisc/kernel/inventory.c:359:1: warning: the frame size of 1120 bytes is larger than 1024 bytes [-Wframe-larger-than=]
